Chemistry - Thermochemistry Question with Solution | TestHub

A mixture of $\mathrm{F}{\mathrm{e}}_2{\mathrm{O}}_3$ and Al is used in solid fuel rockets. What is the fuel value of the mix (in $kcal/mL$)?

Given: $\Delta H_{\mathrm{A}{\mathrm{l}}_2{\mathrm{O}}_3}=-399.0kcal/mol$, $\Delta H_{\mathrm{F}{\mathrm{e}}_2{\mathrm{O}}_3}=-199.0kcal/mol$

The densities of $\mathrm{F}{\mathrm{e}}_2{\mathrm{O}}_3$ and Al are $5g/mL$ and $3g/mL$, respectively.
